STOVE.

SPECIFICATION forming part of Letters Patent No. 634,668, dated October10, 1899.

Application filed December 30,1897. Serial No. 664,553. No model-J Toall whom it vea concern:

Be it known that I, ERNST H. HUENEFELD, a resident of Cincinnati, in thecounty of Hamiltonand State of Ohio, have invented certain new anduseful Improvements in Stoves; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in wood-burning heating-stoves,andis designed more particularly as an improvement on the stove shownand described in my application Serial No. 664,044, filed by me December28, 1897.

In the stove shown in my application above referred to the fire-pot isprovided with removable top and bottom plates held in place by boltspassing longitudinally outside the fire-pot and through both plates.This construction of stove is admirably adapted for the repair of theparts subjected to rough usage and intense heat; but the cost isslightly more than other stoves of the same general character; and theobject of the present in- V vention is to simplify the structure andprovide a stove with a sectional fire-pot so constructed that the partsof the fire-pot can be renewed when burned out or injured, but

'which is more simple in construction and less expensive than theconstruction disclosed in my other application. I

With this end in view my invention consists in the details ofconstruction and combinations of parts, as will be more fully described,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in longitudinal sectionof a stove embodying my invention; and Fig. 2 is a View in horizontalsection, taken on the line .56 w of Fig. 1.

The fire-pot B is preferably cylindrical and i the jacket angular, thesmaller diameter of the jacket being slightly greater than the diameterof the fire pot, thus forming a restricted air-space between the jacketand the fire-pot midway the corners of the jacket and enlargedair-spaces at the corners. I

The collar 0 for the smoke-pipe is provided with a flange 0, shaped toconform to the face of the fire-pot, and with spacing blocks orshoulders 0 which form seats for the jacket A, and thus operate to braceand strengthen the parts and maintain them in-their proper relativepositions. The top plate Z) of the firepot is simply a ring or flangeseamed to the body of the pot and carrying the collar a, integral withthe ring a. This ring a surrounds the fuel-opening in the top plate I)and is removably secured to said top plate by screws and nuts and isprovided with spacing-blocks a integral therewith or secured thereto andforming seats for the top of the jacket.

The fire-pot B is provided near its lower end With a corrugation formingan internal circumferential bead 17 against which the edge of theremovable bottom I) bears. This bottom D is provided with a depressed ordownwardly-turned edge (Z, the extreme edge cl being bent outwardly andslightly upwardly, so as to take under the lower edge of the firepot.This edge (1 of the bottom fits closely within the base of the fire-potB, with its face well up under the bead b which latter closes up anycrevices that might otherwise open into the fire-pot, and thus forms anair-tight bottom and,together with the edge cl, prevents the possibilityof any ashes falling through onto the floor. This bottom is secured inplace within the base of the fire-pot by the bolts E,

passing through the edge or flange d and through the fire-pot and aresecured by the nuts E. As the bottom of the jacket is open, the nuts Eare accessible from the under side of the stove. Hence with thisconstruction it will be seen that the bottom can be removed for renewalor repairs without disturbing or disconnecting any of the parts, thusenabling a damaged or worn-out bottom to be replaced at slight expenseand without the aid of skilled labor.

If desired, I can provide the stove with a damper, such as disclosed inmy application previously referred to, or, if desired, I can employ adoor and provide the same with a flue-box, such as I have shown. Thefirepot is secured to the jacket by bolts passing through the top of thejacket and pot and by bolts around the smoke-flue, and,if necessary, bybraces or spacing-blocks below. I make no claim, however, to the broadidea of a door carrying the flue-box adapted to discharge the airdirectly into the fire-pot, as such construction is claimed in theapplication to J. B. Carter, filed December 28, 1897, Serial No.663,975.

It is evident that various slight changes might be made in the generalform and arrangement of the several parts herein shown and describedWithout departing from the spirit and scope of my invention, and hence Iwould have it understood that Ido not limit myself to the precisedetails herein shown and described, but consider myself at liberty tomake such changes and alterations as fairly fall within the spirit of myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a stove the combination with a jacket open at its lower end, of afire-pot secured to and suspended within the jacket and comprising abody and a bottom the latter having a depending peripheral flange havingan outwardly-turned edge adapted to receive and overlap the lower edgeof the body of the firepot, and removable fastening devices passingthrough the flange and body below the bottom so as to be accessible fromthe under side of the stove.

2. In a stove, the combination with a jacket open at its lower end, of afire-pot secured to and suspended Within the jacket and comprising abody having an internal bead near its lower end, a bottom restingagainst the under side of the bead and having a depending peripheralflange, and removable fastening devices passing through said flange andbody, the said fastening devices being wholly outside the fire-pot andaccessible from the bottom of the stove, substantially as set forth.

3. In a stove the combination With a body, of a removable bottomtherefor, the latter having depending peripheral flange having anoutwardly-turned edge adapted to receive and overlap the lower edge ofthe body, and removable fastening devices passing through the flange andbody below the bottom so as to be accessible from the under side of thestove, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
